Dental practices choosing between cloud-based and on-premises dental software should evaluate five factors: reliability, security, cost, performance, and business continuity. Neither approach is automatically better for every practice.
For a dental office with 10-80 employees, cloud software can reduce dependence on an in-office server and make multi-location access easier. On-premises systems can provide excellent local performance and greater control over infrastructure, but they require the practice to maintain servers, backups, networking, cybersecurity, and hardware replacement.
The right decision depends on how your practice uses systems such as Dentrix®, Open Dental®, Eaglesoft®, Dexis®, digital imaging, panoramic X-ray equipment, and intraoral scanners.
Here is a practical framework for making the decision.
The 5-Factor Cloud vs. On-Premises Dental Software Framework
Before choosing a platform, evaluate:
- Reliability and internet dependence
- Performance and imaging requirements
- Cybersecurity and HIPAA considerations
- Total cost of ownership
- Growth and business continuity
Do not make the decision based only on whether a system is described as "cloud" or "local."
The entire dental technology environment matters.
1. Reliability: What Happens When the Internet Goes Down?
This is one of the biggest differences between cloud and on-premises systems.
Cloud-Based Dental Software
A cloud platform typically depends heavily on internet connectivity.
If your internet connection fails, access to critical applications may be limited or unavailable depending on the software.
That means cloud-focused practices should think carefully about:
- Internet reliability
- Business-class connectivity
- Backup internet
- Firewall reliability
- Wireless performance
- Network monitoring
A second internet connection or cellular failover can be valuable for practices that depend heavily on cloud applications.
On-Premises Dental Software
With an on-premises application, the database may reside on a server inside your office.
Your local computers may therefore continue communicating with the server even if the internet connection fails.
However, local infrastructure introduces different failure points:
- Server hardware
- Storage
- Network switches
- Cabling
- Backup systems
- Power
The question is not:
"Which option never goes down?"
Neither one can promise that.
The better question is:
"Which risks are we prepared to manage?"
2. Performance: How Do Dental Imaging Systems Affect the Decision?
Dental technology uses much more data than a typical office environment.
Your practice may rely on:
- Dexis
- Digital sensors
- Panoramic X-rays
- CBCT imaging
- Intraoral scanners
- High-resolution images
- Treatment planning software
Those systems can create significant storage and network requirements.
A practice management application may work well in the cloud while imaging data is handled differently.
That is why a dental office should not think of its technology as one single system.
You may have:
Cloud practice management + local imaging + cloud backup + local network infrastructure.
That hybrid model can be completely appropriate.
Your IT provider should understand how every component communicates before recommending a migration.
3. Cybersecurity and HIPAA: Is the Cloud Safer?
Not automatically.
Moving an application to the cloud does not eliminate cybersecurity responsibilities.
A cloud platform may shift some infrastructure responsibilities to the software provider, but your dental practice still needs to protect:
- User accounts
- Passwords
- Workstations
- Laptops
- Networks
- Administrative access
- Backups
- Employees
Important controls may include:
- Multi-factor authentication
- Endpoint security
- Unique user accounts
- Strong access controls
- Email security
- Security awareness training
- Device encryption where appropriate
- Incident response procedures
- Reliable backups
A compromised employee account can create problems whether your software is hosted locally or in the cloud.
What About HIPAA?
Cloud hosting does not automatically make a dental practice HIPAA compliant.
Similarly, an on-premises server is not automatically noncompliant.
HIPAA-related decisions should consider how electronic protected health information is accessed, stored, transmitted, protected, and recovered.
When evaluating any cloud dental platform, determine:
- What data the vendor stores
- How data is protected
- How data is backed up
- What security controls are available
- How access is managed
- What backup and recovery capabilities exist
- What contractual responsibilities apply
Your IT provider and compliance resources should help you evaluate the technology in the context of your overall security program.
4. Cost: Is Cloud Dental Software Cheaper Than Running a Server?
Sometimes.
But comparing only the monthly software subscription to the cost of buying a server creates an incomplete picture.
You need to evaluate the total cost of ownership.
On-Premises Costs May Include
- Server hardware
- Server operating systems
- Storage
- Backup equipment
- Backup services
- Warranty
- Power protection
- Server monitoring
- Hardware replacement
- Migration projects
- Electricity usage costs
A server may have a planning lifecycle of approximately 5-7 years, depending on the environment.
That creates a significant periodic capital expense.
Cloud Costs May Include
- Monthly software subscriptions
- Per-user or per-provider fees
- Data storage
- Backup services
- Additional cloud services
- Internet redundancy
- Migration costs
Cloud software can convert some large hardware expenses into predictable recurring costs.
But "cloud" does not automatically mean "less expensive."
A Simple 5-Year Cost Comparison
Consider a hypothetical dental practice with 25 employees.
An on-premises approach might involve:
- Server purchase
- Installation
- Backup system
- Server support
- Hardware warranty
- Eventual replacement
A cloud approach might involve:
- Monthly subscription fees
- User licensing
- Cloud storage
- Increased internet resiliency
- Migration expenses
Instead of asking:
"Which one costs less this month?"
calculate:
"What will each model cost us over five years?"
Then include the business risks associated with each option.
That creates a much more useful comparison.
5. Growth: Which Model Is Better for Multiple Locations?
Cloud applications can be particularly attractive for practices planning:
- Multiple offices
- Remote administrative teams
- Centralized billing
- Shared employees
- Additional providers
- Future acquisitions
Instead of connecting multiple offices back to a central server, users may access the cloud platform through secure internet connections.
That can simplify some aspects of expansion.
However, each location still needs:
- Reliable internet
- Strong networking
- Secure firewalls
- Proper Wi-Fi
- Protected workstations
- Local imaging integration
Cloud software does not eliminate the need for quality IT infrastructure.
When Does On-Premises Dental Software Make Sense?
An on-premises environment may remain appropriate when a practice:
- Has reliable and relatively modern server infrastructure
- Uses applications optimized for local deployment
- Has substantial local imaging requirements
- Wants greater control over certain infrastructure
- Has excellent internal network performance
- Has a strong backup and disaster recovery strategy
- Is not experiencing problems that justify migration
If your existing environment is secure, supported, reliable, and meeting the practice's needs, migration should have a clear business purpose.
"Cloud is newer" is not enough.
When Does Cloud-Based Dental Software Make Sense?
Cloud platforms may be particularly attractive when a practice:
- Wants to reduce dependence on an aging local server
- Is opening additional locations
- Needs easier remote access
- Wants more predictable infrastructure costs
- Is already planning a major technology refresh
- Wants to simplify portions of its IT environment
The strongest migration projects solve a business problem.
For example:
"Our server is approaching replacement, we're opening a second practice, and our current system makes multi-location access difficult."
That is a much stronger reason than simply:
"Everyone is moving to the cloud."
Should You Move to the Cloud When Your Server Reaches End of Life?
That is one of the best times to evaluate your options.
Suppose your dental practice has a 5-year-old server approaching replacement.
You have two broad choices:
Option A: Replace the Server
Continue using your existing application architecture with new infrastructure.
Option B: Evaluate Cloud Migration
Determine whether a cloud version or alternative platform meets your clinical, business, imaging, security, and financial requirements.
The key word is evaluate.
Do not automatically replace the server without considering cloud options.
But do not automatically migrate to the cloud simply to avoid purchasing a server.
Run both scenarios.
What Questions Should You Ask Before Moving Dental Software to the Cloud?
Use these 12 questions.
1. What happens if our internet goes down?
Understand exactly which systems will remain available.
2. Do we need backup internet?
For cloud-dependent practices, redundancy may be worth the investment.
3. Where will our imaging data live?
Practice management and imaging may have different architectures.
4. Will our panoramic X-ray system still work?
Verify compatibility before migration.
5. Will our intraoral scanner integrate properly?
Do not assume compatibility.
6. What happens to our existing patient data?
Understand the migration process.
7. How long will migration take?
Ask what employees and patients will experience.
8. Will we have downtime?
Determine when cutover occurs.
9. How is our data backed up?
Do not assume the word "cloud" means unlimited recovery.
10. What security controls are available?
Ask about MFA, access controls, logging, and account management.
11. How do we retrieve our data if we change vendors?
Data portability matters.
12. What is the five-year total cost?
Compare the full cost, not merely the first month's subscription.
What About Dentrix?
Dental practices using Dentrix should evaluate their specific Dentrix environment before making infrastructure changes.
Important questions include:
- Which Dentrix products are you using?
- Where is your database currently hosted?
- Which imaging systems integrate with it?
- What hardware does your environment require?
- What migration options are available?
- How will existing workflows change?
Do not migrate critical dental software without coordinating with the applicable software vendor and an IT provider familiar with dental environments.
What About Open Dental?
Open Dental environments can also vary significantly.
Before changing hosting models, evaluate:
- Database architecture
- Workstation requirements
- Imaging integrations
- Network requirements
- Remote-access needs
- Backup procedures
A practice should understand the current environment before deciding whether local, hosted, or other deployment options are appropriate.
What About Eaglesoft and Dexis?
Practice management and imaging platforms should not be evaluated independently.
An Eaglesoft environment may interact with:
- Servers
- Workstations
- Imaging
- Network storage
- Peripheral equipment
Dexis environments may involve:
- Sensors
- Imaging workstations
- Storage
- Network performance
- Integration with practice-management software
Before any major infrastructure migration, test and document these dependencies.
The Hybrid Approach: Cloud and Local Technology Together
Many dental practices will not become 100% cloud or 100% local.
A hybrid environment may contain:
- Cloud email
- Cloud collaboration
- Cloud practice applications
- Local imaging systems
- Local network storage
- Cloud backups
- Local workstations
- Cloud cybersecurity management
That is normal.
The objective should not be technological purity.
The objective should be:
reliable, secure technology that supports patient care.
A Cloud vs. On-Premises Comparison
| Factor | Cloud-Based | On-Premises |
|---|---|---|
| Server dependency | Lower local server dependency | Usually requires local infrastructure |
| Internet dependency | Typically higher | Often lower for local applications |
| Remote access | Often easier | May require additional configuration |
| Upfront infrastructure cost | Often lower | Can be higher |
| Recurring costs | Often higher/predictable | Mix of recurring and capital costs |
| Hardware responsibility | More shifted to vendor | More responsibility remains with practice |
| Local imaging integration | Must be evaluated | Often familiar in existing environments |
| Multi-location growth | Often attractive | Can require additional infrastructure |
| Cybersecurity responsibility | Shared across multiple parties | Primarily practice/provider infrastructure |
| Backup/recovery | Must verify vendor capabilities | Must be designed and maintained |
Neither column wins every category.
That is why the decision should be based on your specific practice.

Frequently Asked Questions About Cloud Dental Software
Is cloud dental software better than on-premises software?
Not universally. Cloud systems offer advantages such as reduced dependence on local servers and easier access across locations, while on-premises systems may offer excellent local performance and compatibility with established workflows. The best choice depends on your specific environment.
Is cloud software automatically more secure?
No. Cloud services can provide strong security capabilities, but your practice still needs secure accounts, MFA, endpoint protection, employee training, access management, and reliable IT management.
Do we still need an IT company if our dental software is cloud-based?
Yes. Cloud software does not manage your workstations, networks, firewalls, imaging equipment, Microsoft 365, cybersecurity, printers, scanners, internet connections, or employee support.
Can we keep imaging systems local while moving practice management to the cloud?
Potentially. Many environments use a combination of local and cloud technologies. Compatibility and workflow should be evaluated before migration.
Should we move to the cloud instead of replacing our server?
It is worth evaluating both options when a server approaches replacement. Compare cost, software compatibility, performance, reliability, security, growth plans, and business continuity before deciding.
How important is backup internet for a cloud dental practice?
The more critical cloud applications are to daily operations, the more valuable internet redundancy can become. You should evaluate the financial impact of internet downtime against the cost of maintaining a secondary connection.
